• Social media advertising: placing ads on social media platforms like Facebook, Instagram, Twitter, and LinkedIn
• Display advertising: placing ads on websites through platforms like Google AdSense and Media.net
• Video advertising: placing ads before, during or after a video content on platforms like YouTube, TikTok, and Vimeo
• Influencer marketing: paying influencers to promote a product or service on social media
• Native advertising: Creating ads that resemble the platform where they’re being advertised on, such as sponsored articles on a news website
• Retargeting: Showing ads to people who have previously visited a website
• CPA (Cost per Action) advertising: Paying only when a user completes a specific action, such as making a purchase or filling out a form

Online Advertising services can help businesses to reach and target a specific audience, generate leads and sales, and increase brand awareness.
